This report presents the results of a Bureau of Reclamation hydraulic model study of the proposed high flow bypass (HFB) spillway for Robles Diversion Dam. Robles Diversion Dam is located on the Ventura River approximately 14 river miles from the ocean. A 1:20 Froude-scale model of the proposed facility was tested to determine the interaction of flows and bed load sediments near the facility following decommissioning and removal of Matilija Dam located about two river miles upstream. The HFB spillway was proposed to enhance sediment movement through the diversion pool thereby reducing the impacts of elevated bed load levels resulting from the upstream dam removal. A new auxiliary fishway and 1.5 ft dam raise associated with the HFB is also proposed to improve upstream fish passage at the diversion dam during HFB operation.
